title: "Size" and "shape" variables in the presence of covariates: an application to the sudden infant death syndrome.
abstract: A "size measure independent of shape" is used to investigate differences in "size" and "shape" variables, defined as functions of weight and length at birth, between a random control group and victims of the Sudden Infant Death Syndrome (SIDS). At birth, the SIDS group has a lower mean size than the control group. After adjusting for maternal and environmental factors (covariates), there is a lessened but persistent difference in size, suggesting the existence of some undetected factor linked to sudden death in infants.
